<p>PROBLEM TO BE SOLVED: To provide a water discharge device capable of realizing waterfall type water discharge being long in a distance up to converging.SOLUTION: A water discharge device 1 comprises a water discharge plate 20 for forming a slender water discharge port 21, and the water discharge port 21 is formed so that its opposed long side parts 31 and 32 mutually continuously or gradually separate for approaching both end sides from the central side in the lengthwise direction of the water discharge port 21. The opposed long side parts 31 and 32 of the water discharge port 21 are parallel in the lengthwise direction, and are formed so as to become the relationship of line symmetry with a vertical straight line of passing through the center of short side parts 35 and 36 of the water discharge port 21 as the symmetric axis.</p> |
